i Specification of Letters Patent. P'tlltd Aug, 29, 1922,

Application filed April 13, 1918. Seriall No. 228,351.

To all co 72cm t may concern e Be it lrnown that l, Ann lViLK, a citizen ofthe United States, residing at rloledo, in the county of Lucas and State of Ohio, have invented certain new and useful lmprovements in Spring Seats, of which l declare the following to be a full, clear, and exact description. l

My invention relates to improvements in spring structures for use in upholstering of vehicle and other' seats and cushions, mattresses and the like.

rlhe principal object of the invention is 'to produce a spring supporting structure which is complete'in itself, very easily assembled andeliminates noise caused by the contact of the adjacent springs.

Another object of my invention is to simplify and cheapen the construction of the spring structure without decreasing the efficiency or durability of the same.

Further objects, and objects relating to economies of manufacture and details of construction, will definitely appear from the detailed description to vfollow l accomplish the objects of my invention by the devices and means described in the following specification. My invention is clearly delined and pointed out in the appended claims.

A structure constituting a preferred embodiment of my invention is illustrated in the accompanying drawings, forming'a part of this specification, in which:

Fig. l is a top plan view of a spring structure constructed in accordance with my in- 'ventiorn with part of the top layer of the fabric shown broken away. i

.Figure Il is a horizontal, sectional View through the spring structure, being taken substantially on line ll-ll of lll.

F ig. HI is a detail, vertical, section taken substantially on the line Ill-lllof Fig. l.'

Fig. IV is a detail, vertical section taken substantially on the line lV-lV of F ig. l.

. In general, my invention comprises an improved fabric top and bottom covering,

in which the springs are easily mounted to physically retain the springs in uniform and spaced positions, to Yproduce` a universally yielding structure and prevent noise ydue to the contact of the'adjacent springs.

The to) and bottom coverings each -coi'nprises a layer of fabric on the outside, a

wire margin frame around which the border of thecovering is secured, preferablyT by lines of stitching and spaced parallel strips of fabric secured to the inside of the outside layer of fabric to form receptacles A kfor receiving and` retaining the terminal rings or convolutions of the springs. There is preferably a strip for each parallel row of springs, which are preferably of the hourglass type, and the strips are fastened, preferably by lines of stitching, to the outer layer of thev fabric. The parallel lines of stitching are preferably at right angles to the length of the strips and equally spaced apart, the terminal convolutions of the springs beingpositioned in the receptacles between the lines of stitching to properly maintain them .in position longitudinally of the strips. The longitudinal edges of the strips are not fastened to the outside layer vof fabric, so that the sides of the receptacles the coverings. Means, preferably cords, eX-

tend transversely of the length of the strips and are looped about the wires forming the end convolutions of the springs to properly maintain the springs in uniform positions, transversely of the length of the strips.

ln carrying my invention into effect, l provide a top and bottom layer, l0 and ll. respectively, of burlap or other suitable fabric, of suitable width and length for the struc-taire to be made. The borders of the top and bottom covers arelapped around wire marginal frames l?, and secured by lines of stitching 13 (Figs. l and ll). n the inside 'of each layer of. fabric l0 and ll, spaced parallel strips l-lof any suitable fabric are secured by parallel lines of stitching l5 (Figs. l and Il). The parallel lines of stitching 15 are at right angles to the length of the parallel strips la and are spaced from each other so that the receptacles formed between the top and bottom layers 10 and 'll respectively and the portions of the strips the open sides of the `receptacles as hereto` fore described, and are' thereby held in spaced relation to each other longitudinally ofthe strips la. The. ends of the strips lll may be lapped about the marginal wire with the ends of the outside layer 10 or 11 and fastened to the outside layer by the lines of stitching 13 so that the end springs are held out of contact with the marginal wire 12, the end receptacles being formed by the. lines of stitching 13 and the first line of stitching 15 from each end.

Cords 19, (Fig, l) consisting of a strong fibre and extending' transversely across the strips let are looped about the adiaccnt portions of the end convolutions 17 of the springs 18 as indicated at 19 and the end portions of the loops project through the outer layer of fabric 10 or 11, l cord for each transverse row of springs may be used or a single cord for each covering may be used in which case the ends of each transverse portion of the cord are looped about the border wire 12 and the terminal coils of the end springs. These cords hold the springs 18 in spaced relation transversely the length of the springs.

lt is apparent from the above description that when the springs 18 are properly sembled on the top and bottom coverings 10 and 11, and the cords 19 are secured, there is then no possibility of metallic contact between the springs, whereby it follows that the structure is practically noiseless when in use and the highest resilient etliciency of the springs can be obtained. ln forming the assembled structure the top and bottom coverings are first made and then sewed on the respective marginal wire frames 12. The springs are then applied to the covering by clipping their end convolutions into the receptacles formed in the coverings. Finally the cords 19 are applied to the coverings and springs.

I am aware that the particular embodiment of my invention is susceptible of considerable variation without departing from the spirit thereof, and, therefore, l desire to claim my' invention broadly, as well as specifically, as indicated by the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:
